HAT-MACHINE TOOL-COUPLER.

SPECIFICATION forming part of Letters Patent No. 317,426, dated May 5,1885.

Application filed September 4, 188-1.

. ner as to traverse an uneven or elliptic path in reference to the bodyof the rotating hat, and in a vibrating coupling device for connectingsuch tool-carriers, so that both will participate in any movement thatmay be imparted to either.

In order that different tools may be successively used in such coupledcarriers, itbecomes necessary to provide means for adjusting one or bothof the carriers or tools in relation to the coupling devices; andthisinvention therefore includes such means of adjustment, as well as astop for determining its limit.

It also includes means for compensating the lost motion in the couplingdevice, means for withdrawing the tools from the hat-plate, both forremoving the hat and changing the plate, means for supplying air and gasto the heatingburners, and the combination and arrangement of variousdetails of construction. These improvements will be understood byreference to the annexed drawings, in which Figure l is a frontelevation of a machine illustrating our invention as applied to a pairof the rocking arms described and claimed in anotherpatent application,No. 142,205. Fig. 2 is a view of the rear part of the frame, showingmerely the coupler and the gas-connections. Fig. 3 is aside view of theentire machine. Fig. etis aplan of the same. Fig. 5 is a side view, andFig. 6 afront view, of the rocking arm detached from the machine, theside view including the nut for the setting-screw, the clamp-nut, therock-shaft, and one segment, and the front view including thecarrierguide and its adjustable supporter.

ler. Fig. Sis a plan of the same with the roller removed, and showingthe setting-screw; and Figs. 9, 10, and 11 are a side view, plan and endview of certain parts of a machine, with rectilinear vibrators, showingan alterna- 5 tive mode of applying the coupler to two such vibrators.

In Fig. 10 the tool carriers and their guides are omitted from the view,and Fig. ll exhibits merely the outer end of one of the carriers,guides, and rectilinear vibrators.

The invention is shown herein as applied to ahat-curling machineprovided with two tools mounted at opposite sides of a rotating hatclampand hat-plate for supporting the brim of the hat; but as the inventionis equally applicable to machines for ironing hats, and for trimming,softening, and paring brims, wehave used general terms for the variousparts of the construction.

In Figs. 1 to S, inclusive, A is a pedestal of T section, provided witha flange or foot, A, a hearing, A", at the top for the spindle of thehatplate, cam, and clamp, front and rear bearings,

A and A for the driving-shaft, and side eX- tensions carrying bearings Efor the rockingshatts. The hat'clamp B is mounted at the top of thepedestal on a spindle, B, in the bearing A It may be made of any desiredconstruction, but is assumed to be of the expansion brow-block class;and a hand-wheel, B is shown in Fig.1 for actuating such block andclamping the hat, either with or without the hat-plate 13 Gears Bconnect the spindle B with the driving-shaft G, the front end of whichextends through the pedestal, with the remainder fitting into and beyondthe horizontal bearings A and A, the rear one of which is enlarged toreceive a sleeve, 0, which is formed with a pulley, O, at its outer end,and a toothed hub, c, at its inner end.

Between the bearings A A is located a toothed clutch, 0 which isfeathered upon the shaft 0, so as to rotate the shaft when the clutch isengaged with the toothed hub c, the 5 pulley O being driven continuouslyby a belt. (Not shown.) A clutch-lever, 0 is j ointed to the pedestaland to a shifter, G which projects to the front of the machine, beneaththe hatclamp,.so as to be readily reached by the oper- IOO ator, theclutch being shown uncoupled in the drawings, as in Figs. 3 and 4. Withthis construction the driving mechanism is confined entirely to the rearof the machine, and the hat-clamp is so located at the top of thepedestal as to be peculiarly accessible to the operator. The tools 1)shown as curling-irons herein are represented as held by carriers D,which latter are movable to and from the hatclamp in guides 1). Theseguides are pivoted to rocking arms or holders G, at I), in such mannerthat the carriers swing freely up and down, so that the tool may restupon the hat by its weight alone, when desired.

in the drawings two rockingarms are shown, one hinged at each side ofthe hat-clamp upon rocking shafts E E, the latter beingjournaled inbearings E E, projected from opposite sides of the pedestal A, and thevibrating ends of the arms being extended opposite the sides of thehat-clamp, so as to sustain the toolsin contact with the hat.

The coupling device consists in a pair of toothed segments, F, securedto the rear ends of therocking shafts upon their adjacent sides, withthe teeth on the segments interlocked, so that when either of the armsor holders 1's oscillated a precisely similar movement is imparted tothe other.

To press the tools toward the hat-clamp, a weight, W, is shown attachedto one ofthe segments in Figs. 2, 8, and 4 by a hook, W. Withsuch-construction but one connection is required between the holder andthe cam or other oscillating device, and such connection is shown as avibrator-arm, H, pivoted upon the same center as one of the rocking armsG, and

provided with aroller,H,arranged to bear upon the edge of the hat-plate13 which plate has its edge suitably shaped to act as a cam, B andimpart the desired oscillating motion. The vibrator is furnished withacurved slot, 0/, to fit a clamping-b0] t, a, inserted through the armG. As the vibrator H has a uniform stroke, while the arm or holder Gmust hold the tool nearer to or farther from the clamp to suit brims ofdifferent widths, means is required for setting the arms in variousrelations to such vibrator. A setting-screw, a is therefore fitted to abearing, a and nut a upon the arms G and H, respectively, to set therocking arm in any desired relationito the vibrator, as may be requiredto set thctool into an operative position at any desired distance fromthe center of the hat-clamp. This means of adjustment is for a purposetotally different from the movement of the carrier to and from thehat-clamp in its guide, that movement being intended merelyto clear thetools from the hat and not being necessarily combined with any means forsecuring the carrier in various positions intermediate to its extremesof movement. The clamp-bolt a serves to bind the holder or arm G rigidlyto the vibrator or arm H, after the former has been adjusted for anyspecific tool or hat, by

turning the setting-screw a To guide the operator in thus setting theholder, we commonly use a graduated scale affixed to the arm G or H, buthave not shown the same herein, as we have made it the subject of aseparate patent application.

To move the toolcarrier in its guide, we have shown the former providedwith a rack, b upon its lower side, adjacent to the pivotal shaft 1),and provide the latter with a toothed pinion, b and with a head adaptedto receive acrank, L as shown in Fig. l; or a hand-wheel may be aflixedthereto. The rear end of the carrier is provided with an ad justablestop, b, projecting from its bottom at such point as to strike the guideI) when the carrier is properly set.

With the cur'lingtools shown herein the machine is operated as follows:A hat of known size and width of brim is secured upon the hat-clamp, andboth the carriers thrown forward by turning the pinions b and moving thecarriers until arrested by the stops 1). The clamp a is then loosened,and the setting screw (0 is turned until either of the tools iscorrectly set to operate upon the hat-brim. The other tool is thenadjusted to operate simultaneously by altering its stop b and movin gthe carrier into the required position. \Vhen correctly adjusted, thehat may be curled, and the tools thenbe quickly retracted to remove thehat by turning the pinions b". The provision ofthe stop will thenobviously afford the means of restoring the tools to the same operativeposition for any number of similar hats, provided the tools areunchanged; and should it be necessary to change a tool upon one or bothsides of the hat, the stop then affords the means to adj ust such toolcorrectly and to re set it repeatedly in the same position.

By the coupling of the tools together the vibrating mechanism is notonly-simplified, but it is also obvious that the motion of one tool willcorrespond more accurately with that of the other than if moved byseparately vibrating agencies. This is of especial importance in thecurling of hats, particularly when the curl is formed by tools actingindependently of the hat-brim plate, as the curl is then supported onlyby the tools and is distorted when the two tools do not follow the samecurve.

The coupling of the tools together also secures a great advantage inadvancing the tools simultaneously while the machine is in motion, ascertain operations like curling may be much more easily and perfectlyperformed if the action of the tools upon the brim is gradual. Suchapplication of the tools may be made with our construction by looseningthe clamp to sufficiently to permit the action of the setting-screw, andthen setting the tools into their primary operative position. Thecurling may then be commenced without tightening the clamp, and thetools may be simultaneously and gradually advanced during the progressof the work until the tools reach their final operative position and thecurlingis completed.

In Fig. 1 the tool at the right-hand side is shown in its operativeposition, and a breaker,

f, hinged to the top of the guide I), is shown in suitable position toco-operate with the curlingiron b. At the left side, however, the stopat the rear of the carrier is shown retracted, and the breaker turned upabove the guide to remove the hat. The stop b is thus exposed moreclearly to View, and consists, as is also seen in Figs. 3 and 4., of aflat piece notched into the rear end of the carrier, and held thereto byan adjusting-screw, which has a round milled head, 8. The lower end ofthe stop projects below the carrier, and thus strikes the body of theguide D when the carrier is thrown forward. The sliding carriers, beingintended merely to retract the tools when replacing the hats, need notbe constructed to draw entirely away from the top of the hat plate B andto secure any further withdrawal of the tools, so as to remove thehat-plate, it is desirable to move the vibrator itself from contact withthe plate and hold it back, with the affixed rocking-arm, by a suitablecatch attached to the pedestal A. Such catch is shown in Figs. 1, 3, and4, as a sliding spring-bolt, e, inserted in a boss, 0, upon the top ofthe bearing E, behind the vibrator-arm H, and the latter is formed witha hole, e corresponding with the bolt when the vibrator is drawn back,as described. When thus drawn back, the bolt is automatically shot intothe hole c by a spring, 6", inclosed in the boss 0. The coupler thusoperates, when the single vibrator-arm is drawn back, to hold both therocking-arms backward at once, and to withdraw the tools entirely awayfrom over the hat-plate. The hat-plate may then be readily removed fromthe clamp, it made detachable, and others of different shape at the edgebe substituted, so as to actuate the tools in any desired curve. Aknob,c, is shown fixed to the end of the bolt by which it is pulled backfromthe hole 0 when the machine is again ready for use. The springcatch.may be applied to the vibrator in other ways, as its essential featureis its automatic action when the vibrator is pulled back into aninoperative position.

The term vibrator applied above to the arm H may obviously be construedto cover any means by which the required vibratory movement is given tothe tool carriers or holders, and as it is common to actuate thevibrator in various ways in other machines, the arm H or either of thearms G may be vibrated by any other suitable meams that may be preferredTo illustrate a modification of the vibrator and coupler, we have shownin Figs. 9, 10, and ll a machine constructed with rectilineal vibrators,to which a segmental coupler could not so readily be attached. In thesefigures the tool-carriers and pivoted guides are the same as in theother figures; but the holders G are shown as dovetailed slides fittedto fixed ways G upon a bed, A ,at opposite sides of the clamp, andaseparate cam, B is atfixed to the spindle B beneath the plate B Thevibrator consists of a bar, H, fitted to one of the holders G by ascrew, it", and carrying a roller, 11, in contact with theseparate cam BThe holders are coupled together by means of links F and by a centrallever, F, pivoted upon the spindle B, the inner ends of the links be ingattached to the opposite ends of the lever, so as to move in the equaland similar manner required for tools applied at opposite sides of thesame hat. The weight V is in this construction attached to a cordcarried over a pulley, w, and secured to the holder G opposite thevibrator H. The weight thus serves not only to press the tools towardthe hatclamp and the vibrator toward the cam, but, as it acts inopposition to the latter, it operates to neutralize all the lost motionin the joints of the links F, and thus secures the most exactcoincidence in the movements of the coupled tools. The same effects aresecured in the machine with coupled rocking arms by attaching the.weight to the segment F most remote from the vibrator, as shown in Fig.2. If preferred, the weight W may be replaced by a spring, without,however, securing such uniform pressure.

In practice we make the weight in sections, and apply only enough toforce the tools against the felt and bend or operate upon it in thedesired manner. The roller H provided upon the vibrator isquiteimmaterial, asits function is merely to reduce the friction, and abearing-shoe is used in other machines fora similar purpose.

From the above illustrations it will be seen that the coupler, thevibrator, the toolcarrier, and other mechanical elements of ouriuventionmay be materially altered in form to perform the same function indili'ereut machines; and we do not therefore limit ourselves to theconstructions shown'hcrein for carrying out our invention.

In the machine shown in Figs. 9, 10, and

11 the setting-screw a is used effectively without any clamp-bolt a, andthe latter is not essential to the operation of the arms G and H whenunited by the screw a as shown in the other figures. TheIterm hat clampis used herein as an equivalent for any means whatever that may beadapted to rotate the hat in proximity to the tools, and is nottherefore specifically described or claimed.

In Figs. 1, 3, and at are shown two treadles, I, pivoted separately tothe standard A near its base, at h, and connected separately to thejointed tool-carriers D by means of connecting-rods l; the rods beingpreferably fitted to the treadles by ball-and-socket joints on tocompensate for the various movements of the treadles and carriers, asthe latter are applied to and removed from the hat.

By pressure upon the treadle at the latter stage of the curlingoperation the workman may compress the curl with any degree of force,and thus greatly aid the iron, especially in forming such curls as theAnglsea,

which are pressed down flat upon the hat-brim, to thoroughly break thebend or fold of thefelt. A ball, 1, (shown in dotted lines,) upon anextension, 1 of the treadle lever, behind the fulcrum, may be used, ifdesired, to balance a part of the weight of the tool or carrier.

By the use of independent treadles the opposed tools may be actuatedseparately, and

are thus better adapted for performing different operationssimultaneously upon the same hat, as required in many processes.

In Figs. 1 and 12 is shown a gasjet of special construction, adapted toproject a flame into theheated tools from some external point. Theconstruction consists in anozzle, f, screwed into a socket, g, each ofthese parts being formed with a separate pipeconnection, cl, and one ofthem being provided with a shank, g, for attaching the jet to the toolholder or carrier adjacent to the flame-opening in the iron. The shankmaybe formed at any angle with the pipe-connection as maybest suit thelocation of the flexible tubes, g (Shown in Figs. 1, 2, and 3.) Theemployment of the shank is shown in Fig. 1, where the jet is shownsecured thereby to the carrier D in the rear of the curling-iron I), andthe flexible pipes areindicated as projecting at the rear of the jet.The socket consists in a chamber into which the gas-pipe connectionopens, an d is formed with a contracted outlet, 9 in which the nozzle iscentered. It is also formed with a threaded opening,'t', opposite theoutlet, for the attachment of the nozzle, the point of which is set evenwith the mouth of the outlet g The central bore of the nozzle ispenetrated by the air-connection, so that an airblast may be forciblyprojected from the nozzle into the midst of the gas which issues fromvthe annular space in the socket about the nozzle. W e find that thisconstruction of jet produces a smokeless flame like a blow'pipe, andthat the iron is thus much better heated than when the burner isinserted within it.

We are awaretha-t a gas and air jet is old, and therefore claim only theparticular construction herein described.

We are aware that it is common to change the form of a brow-block or ofa mold for curling and shaping hat-brims by mechanism which operates toexpand or contract the opposite parts equally and simultaneously, andthat similar mechanism has been used to press opposed dies or toolstoward a mold. We do not therefore claim, broadly, the means forconnecting or moving two opposed tools; but, having fully shown thenature of our invention herein, it will be observed that it differs fromany previous construction in providing a vibrating coupler adapted tooperate vibrating tools and tool-carriers, and that it thus affords themeans to dispense with one of the cam rollers or vibrators heretoforeused in machines having two tool-carriers vibrated at opposite sides ofthe same hat. It is therefore restricted to a vibrating coupler appliedto vibrating toolcarriers, the vibrating motion of the latter beingintended to traverse the tools in an elliptical or irregular path abouta rotating hat, and the invention. being therefore claimed incombination with a rotatin g hat-clamp. The rocking arms are alsoclaimed herein as vibrating rocking arms.

We are aware that machines have been heretofore patented in which arotating hatclamp is combined with various forms of tool carriers,holders, and vibrators, and do not therefore claim such parts, broadly,as our invention, but only the novel combinations or constructionsherein described.

We have restricted our claims herein to the stop I) and catch 6,exclusively, in combination with a pair of holders or carriers coupledtogether, as we have claimed the same otherwise in another patentapplication, No: 142,205, of E. Tweedy and Geo. Yule, and Nos. 142,202and 142,204, ofGeo. Yule.

We have also claimed in other pending apbination, with a brim-supportingplate, of a curling-tool resting freely upon such plate, and operated bya vibrating holder and toolcarrier.

It is obvious that certain parts of our invention may be used withoutthe others, and, as we havefully described their separate functionsabove, we claim the same in the follow- 1ng manner:
